Des algorithm in detail

WebThe data encryption standard, or DES, is an encryption algorithm that converts plaintext into blocks then uses a key to convert it to ciphertext. DES is based on an earlier cipher by cryptographer Horst Feistel, called Lucifer. Developed in the 1970s, Lucifer was one of the earliest block ciphers. WebData Encryption Standard is a symmetric-key algorithm for the encrypting the data. It comes under block cipher algorithm which follows Feistel structure.

WebS-DES depends on the use of a 10-bit key shared between sender and receiver. From this key, two 8-bit subkeys are produced for use in particular stages of the encryption and decryption algorithm. First, permute the key in the following fashion. Let the 10-bit key be designated as (k1, K2, k3, k4, k5, k6, k7, k8, k9, k10). WebMar 14, 2024 · DES is a symmetric key algorithm used to encrypt digital data. Its short key length of 56 bits renders DES too insecure to secure most current applications that is based on encryption. DES uses block cipher technology to change fixed-length bitstrings into same-sized, encrypted bitstrings.
